Hoya 900nm infrared filter, Rolleiflex bay1 polarizing filter

Finally I get to sell all those little things I don't use. Up for grab are:

True 900nm infrared filter by Hoya. 49mm diameter. Was sold at B&H and Amazon for $275 or so. Comes with a 52mm step-down ring. No scratches, just some minor cleaning marks. Asking $100 with free shipping anywhere in US or Canada

Spiratone Polarizing filter set for TLRs. There are 2 filters that fit on your Rollei or Yashica and they are geared. So you rotate the filter to see the effect through the viewfinder and you know it would look the same in your photos.
Fits Rolleiflex T, Yashica D and other cameras with Bay 1 mount. Great condition, with case. Very rare. Asking $100 with free shipping.
